MAX materials and MXene materials are new two-dimensional materials that have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in lots of fields. The following is a detailed overview of the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is a layered carbon nitride inorganic non-metallic material comprising M, A, X elements around the periodic table, collectively called “MAX phase”. M represents transition metal elements, such as titanium, zirconium, hafnium, etc., A represents the key group elements, such as aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is made up of M, A, X, three of the components of the alternating composition arrangement, with hexagonal lattice structure. Because of the electrical conductivity of metal and strength, high-temperature resistance and corrosion resistance of structural ceramics, these are commonly used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding as well as other fields.
Properties of MAX material
MAX material is actually a new kind of layered carbon nitride inorganic non-metallic material with the conductive and thermal conductive qualities of metal, consisting of three elements with all the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers back to the transition metal, A means the main-group elements, and X refers to the components of C and N. The MXene material is actually a graphene-like structure obtained by the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. MAX phases are novel two-dimensional nanomaterials composed of carbon, nitrogen, oxygen, and halogens.
